Cons
Con Not completely freeware
If you use MobaXterm at work, they hope you will pay for it. This isn't horrifying, but it's not providing any new features in Linux to warrant the outlay. Its integration with Putty in Windows as an X client may make it worth the funds.
Con Split screen prevents tabbed mode
If you split a screen within a tab, you have to go back to single screen before you can switch to another tab.
Con Can have some performance issues
MobaXterm can have some occasional performance issues. These happen rarely but it's worth mentioning that they exist, especially since this is a paid tool.
